Re: [hylafax-users] Failed to properly detect high-speed data carrier



Kimble,

I have considered replacing the fax machine that produces these errors and will if that is the final solution. Being new to Hylafax, I was worried that the machine I replace it with might also show up with the same errors -- then I would be in a bit of a pickle. How do I say this without it coming out wrong? -- It is easy to tweak Hylafax and the modems via the config. It is very difficult to decipher the problem via the logs (looks like a foreign language to me.) For that reason I thought this was a good starting point (experts with experience might have some suggestions.) I could just start swapping hardware until the problem goes away, but won't be able to do that in every case.

Lee,

I am getting the logs together. I have two receiving Multitech modems that both have trouble receiving from this same sender. That really makes it seem like I need to replace that Brother fax machine. But, if that machine wasn't in an office I could control, I would be in trouble.

I appreciate both of your comments and help!

Kimble,

I agree with your advice.

However, in this case I see an opportunity to investigate a possibility of improving HylaFAX. On the systems I administer I see a little less than 1% reception errors. Half of those are due to "failed to properly detect high-speed data carrier" errors that look rather similar to the log that John has posted. I've investigated these problems on one production server before, but I had to test long, long periods of "random" and "occassional" errors to try to determine what was going on, and in the end I found no useful result. If John has a scenario that can reproduce the problem, then maybe I can find an answer more easily this way.

Thanks,

Lee.

John,

Ever considered that it might be cheaper both time and money wise to just replace the one dodgy fax machine rather than pull your hair out. You did mention it was a remote office so I assume you have some say in the matter.

All,

I am sorry to post this problem to the list. I am getting the error "Failed to properly detect high-speed data carrier" with a just purchased Multitech MT5600ZDXV after also receiving the error with a Multitech MT2834ZDXb (Class 2 only). I have read through the archives and tried several of the suggestions therein, but continue to experience this problem.

It seems I always get this error from the same fax machine, one in use in one of our remote offices (Brother Model MFC 4800).

Though we receive approximately 100 faxes per day on the Multitech modem, we get errors on every single fax from the Brother fax machine, and occasionally see this error from other numbers (albeit
